把 SDK 指向我們的 Base URL，並傳入你的 cheapaimodel Key，其他一切照舊。

## 環境變數 [#環境變數]

這些 SDK 也會讀取 `OPENAI_BASE_URL` 與 `OPENAI_API_KEY`，對建構在它們之上的工具很方便：

```bash title="終端機"
export OPENAI_BASE_URL="https://api.cheapaimodel.ai/v1"
export OPENAI_API_KEY="$CHEAPAIMODEL_API_KEY"
```

可把 `deepseek-v4-1-flash` 換成[目錄](/zh-Hant/models)中列有這些端點的任何模型。
